IMPROVEMENT IN CULTIVATQRS.

Specification forming part of Letters Patent No. 135,148, dated January 21, 1873.

To all whom it may concern:

Be it known that I, JAMEs H. Pn'rrnn, of Monmouth, county ot' Warren and State of Illinois, have invented certain Improvements in Cnltivators, of which the following is a speciiication Nature and Objects of the Invention.

The nature ot' my invention relates to improvements in that class of eultivators known as corn-cultivators, and for improvements on .which a patent was granted to me March 3,

187 2. My present invention consists in a new and improved device by means of which the braces which connect the standards with the plow-beams are securely held in position and readily adjusted so as to increase or lessen the angle and consequent depth of penetration of the plows or shovels. It also consists in a new and improved coupling device or joint by means of which the plow-beams are hinged to the axle, all as hereinafter more fully set forth.

Desert tion o the Accomoam in( Drawin Figure l is a perspective view of a machine embodying my invention. Fig. 2 is a rear elevation of the axle and wheels and a vertical section of the coupling-plates on the line a: a?. Fig. 3 is a longitudinal vertical sectional view of the end of one beam and the coupling devices. Fig. 4 is a horizontal sectional view of the end of one beamand the coupling devices. Fig. 5 is a detached view of ratchet-plate on one of the beams for adjustably securing the standard-brace thereto. Fig. 5 is enlarged.

General Description.

A represents the axle, consisting of an elevated central portion, A, vertical side pieces A A ,Y and horizontal projections a a from thc lower end of each ofthe vertical side pieces A A. B B are vertical coupling-spindles, two of which are secured between each pair of projections e a. G G are open-framed triangularshaped draft-plates, having snu gs c c, by which they are pivoted to the outer ends of the projections a e, and provided at their forward ends with hooks c c', to which the draft-animals may be attached. D D are the wheelspindles, secured to and projecting from the outer sides of the plates C C. E E are the supporting-wheels, carried on spindles D D. G G are the plow-beams H H H H, the stand. ards, secured to the beams G G at their upper ends by a single bolt, It, and may have secured to their lower ends any ot' the ordinary shovels, I. J J arethe handles. K Karethebraces from the standards to the beams, and are attached and rendered adjustable in len gth' as follows: Their ends, next the standards, are secured by a bolt, 7c, which passes through a hole in the brace and sidewise through the standard, and their upper ends are secured to adjustable ratchet-plates L L by a wooden break-pin, l.

Two methods, substantially the same, are shown in the drawing for adjusting the ratchet-plates L L In the one shown at L a plate, M, is secured to the beam between the'plate L and the beam, and the adjacent faces ofthe plates L and M are formed with corresponding transverse ratchet-teeth, which engage with each other. The plate L is also provided with a longitudinal slot, through which a bolt, m, passes, also passing through the plate M and the plow-beam, and lhas a nut, m', on its outer end.

It will be evident to any one skilled in the art that by loosening the nut m the plate L may be moved to set the standard H at any desired angle, and the ratchet-teeth being fine the variations may be very slight, thus enabling the operator to set the standards so as to make the plows run evenly and regular.

The braces K are of cheap construction,be. ing simply dat iron straps with a hole in each end, and the method of attaching them to the standards, by a bolt passing through sidewise, will tend to strengthen the standard and prevent it splitting, as is often the case where the brace passes back through a hole or slot therein, or when it is attached to a plate secured to the standard by a bolt passing through the the plate L by a wooden break-pin, l, and to the side of the standard H by a bolt, k, which passes sidewise through the standard, the same as hereinbeiore described. The adjustment of the plate L is effected by loosening the nut m" and rotating the plate L on the plate M, and admits of Very slight variation in the angie of the standard to the beam if the ratchettecth are ne, the same as the plate L. The ratchet-teeth in the plates L and M when tightened up by their bolts and nuts, will hold the plate L securely from moving by the strain on the standards when in use. The operation of the wooden break-pins is the same as in ordinary cultivators. N N are the beam-plates, one on each side of the forward end of each beam, and theirforward ends brought together, forming a fiat plate. l? P are plates, partly encircling the coupling-spindles B B, on which they turn to allow the necessary lateral movelment of the plow-beams, their ends extending back and clasping the projecting ends of the beam-plates N N, to which they are pivoted by a bolt, n,on which the beams have vertical movement. n n are annular iianges on the sides of the beam-plates N N and around the holes for the bolt a, and n n are corresponding recesses in the adjacent facesof the plates P P for relieving the bolt n from the strain of the draft. (See Fig. 4.) lt is a bolt through the plates P, just forward of the ends ot the beam-plates N. The ends of the beam-plates N have a segmental annular recess cut therein, the ends of which engage with the pin or bolt R and sustain the axle in a nearly vertical position, at the same time allowing the plowbeams limited but sufficient vertical oscillation. (See Fig. 3.) The plates-P P have projections p p on one side, (see Fig. 3,) so that by inverting them the vertical adjustment to change the depth of running may be regulated, and the adjustment of the beams laterally or distance apart may be regulated by attaching to the different spindles B B.

The axle A being hinged directly to the plates C C, which carry the wheel-spindles, the same as in my aforesaid patent, their operation and relative changes of position are, of course, the same.
